Automated whole heart segmentation using U-Net in pediatric cardiac CT achieved a mean Dice similarity coefficient over 0.95 across all age categories.
Does automated heart segmentation using U-Net provide accurate segmentation in pediatric cardiac CT images?
Deep learning using U-Net provides highly accurate automated whole heart segmentation in pediatric cardiac CT across various age groups.
This study investigated the usefulness of deep learning methods for segmenting the whole heart region and the cardiac cavity region in pediatric cardiac CT images using U-Net. Dice similarity coefficient (DSC) was used to evaluate the segmentation accuracy by leave-one-subject-out cross-validation. The mean DSC for the whole heart was over 0.95, and analysis of variance among the four age categories (less than one year, 1y to 4y, 5y to 9y, 10y to 14y) showed no significant differences. The mean DSCs for each chamber were 0.78–0.88 when they were trained in a lump. The corresponding DSCs were 0.80–0.85 when they were trained separately. Although the size and shape of the heart varied with age in children, whole heart segmentation using U-Net showed high DSCs in all age categories. Deep learning would become a useful elemental technology in heart segmentation of pediatric cardiology.
Yoshida et al. (Fri,) conducted a other in Pediatric cardiac CT. U-Net deep learning method was evaluated on Dice similarity coefficient (DSC) for whole heart segmentation. Automated whole heart segmentation using U-Net in pediatric cardiac CT achieved a mean Dice similarity coefficient over 0.95 across all age categories.
